"Determination Of Trace Elements In Unalloyed Steels By Flow Injection Inductively Coupled Plasma Mass Spectrometry"
J. Anal. At. Spectrom. 1995 Volume 10, Issue 6 Pages 449-453
Aurora G. Coedo and Teresa Dorado

Abstract: Steel (250 mg) was treated with 7 mL 65% HNO3, 200 µL 40% HF and 3 mL water and the mixture was digested in a microwave oven (program details given). The oven was cooled, the contents were transferred to a calibrated flask and 2.5 µg each of Be, Tl and Rh (internal standards) were added. The solution was diluted to 50 mL with 1% HNO3 and a 250 µL portion of the solution was pumped into the nebulizer (2.8 ml/min), mixed with the nebulizer gas (1.1 ml/min) and analyzed by ICP-MS (operating conditions given). The RSD was 3% for all analytes at concentrations 1 µg/g. The method was applied to the analysis of two pure Fe reference materials (BCR CRM 097 and NIST SRM 365). Results agreed well with certified values.
